Quantification of EPA 1694 Pharmaceuticals and Personal Care Products in Water at the ng/L Level Utilizing Online Sample Preparation with LC-MS/MS

Instrument Type: LCMSMS

There is growing environmental concern regarding the health impact of trace levels of pharmaceuticals and personal care products (PPCPs) in water resources. In response, the U.S. Environmental Protection Agency (EPA) published Method 1694, which determines dozens of PPCPs in water, soil, sediment, and biosolids by HPLC-MS/MS. We demonstrate a progressive approach to analyzing PPCPs in environmental sources of water at the ng/L level with online sample preparation using small volumes of water, thus saving time and reducing the cost of analysis.

AN1142: Determination of Aluminum in OTC Pharmaceutical Products

Instrument Type: IC

Aluminum-containing compounds are used extensively in cosmetics, prescription pharmaceuticals, and OTC drug products. In this application note, we report the validation of an IC method for the determination of aluminum in OTC formulations using a Dionex IonPac CS10 analytical column and postcolumn derivatization with Tiron, followed by UV absorbance detection at 310 nm. The method was evaluated in terms of linearity, precision, accuracy, ruggedness, and limit of quantitation for aluminum. The method was evaluated with antacids and deodorants. An ICS-6000 can be used for this application.

Fast analysis of antacids using a Thermo Scientific Hypersil GOLD Phenyl HPLC column

Instrument Type: HPLC

The Thermo Scientific HPLC system is applied for the analysis of antacids. The separation is performed on a Thermo Scientific Hypersil GOLD Phenyl HPLC column, with UV detection at 254 nm.
